Sewage pumping station (SPS): the right choice and do-it-yourself installation. Installation rules for sewage pumps Installation of a sewage pumping station

The topic of sewage can only seem unpleasant to an inexperienced homeowner and only at first glance. As soon as problems arise with the sewerage system, their elimination becomes the most important task.

If troubles with stocks are of a regular nature, it makes sense to revise the original project for errors. To eliminate them, you may need a pumping sewer station. We will show you how to install, operate and maintain it.

SPS or sewage station is a device for the forced removal of solid and liquid effluents. Such devices are most often used for industrial purposes.

But there is whole line SPS specially designed for operation in living conditions... They are usually installed in private households with or where it is necessary to ensure the transportation of waste to the riser of a centralized sewer system.

There are compact models of sewage pumping stations that can be installed under the kitchen sink. But connect a washing or dishwasher it is forbidden

Should be considered allowable temperature drains set by the manufacturer for each specific model. So, sewage pumping stations, into which warm, but not too hot, wastewater can be drained, are suitable for connecting to a shower cabin, bath, toilet, bidet, kitchen sink etc.

However, if there is an automatic washing machine, you should choose a model of a sewage pumping station for your home, into which you can drain wastewater with a temperature of 90 degrees or higher. It should be borne in mind that the mode of operation of such a technique usually involves boiling.

All this also applies to the dishwasher, from which an almost boiling liquid can flow into the drain. In addition to the current needs of the house, you should evaluate your plans so that you do not have to buy and install a new sewer station.

If you intend to purchase a dishwasher in the future, it is better to immediately choose a sewage pumping station designed for drains with a high temperature.

Pay attention to the number and location of the pipes. For each new household device that needs to be connected to, which may appear in the future, there must be a corresponding branch pipe. Otherwise, there will simply be nowhere to connect it.

Conclusions and useful video on the topic

An overview of the compact toilet waste station is presented here:

This video schematically shows the installation process of a large SPS:

A sewer station can dramatically improve your home's life. It is important to choose correct model SPS and install it correctly. Correct operation and regular maintenance will ensure that there are no problems with this useful device for many years.

floor, but if this equipment is average in size, then a pit is being dug for it or it will be necessary to place it in special room KNS.

Today we will focus on the arrangement of the pit, including all regulatory components, namely:

Sanitary protection zone of the sewage pumping station, which must be observed within the established standards (about 15 m).

The requirements for the fencing of the sewage pumping station, if it is buried, can be observed, cleanly, due to safety measures or the safety of equipment, and so they put a lock on the cabinet and hatch, and that's it.

Observe the safety rules, and therefore, during the construction of the pipeline and the pit, in order to avoid traumatic situations, it is necessary to build barriers for the working area.

For the installation of a pump station, the estimate should include all the estimated costs:

for renting special equipment for digging a pit and installing equipment;
for the purchase and delivery of sand with concrete for the foundation of the sewage pumping station;
for related tools and parts for fastening the tank;
to pay a team of workers, if you do not plan to carry out the installation of a sewage pumping station with your own hands, etc.

And so, you have taken into account all of the above and are ready to proceed with the installation itself:

A pit is being dug, in size exceeding the dimensions of the SPS structure. This is necessary for convenient connection of the rest of the pipeline and power supply.
In order not to dig the soil, the most lower part holes are dug by hand.
According to the drawing, a formwork is being built: a sand cushion (10-15 cm) is made, reinforcement is installed and concrete is poured in several layers, using a level in order to make the foundation as horizontal as possible.
Only after the reinforced concrete structure has completely hardened, the body is attached to it, taking into account that when installing the KNS, the deviation from verticality is permissible within 5 mm.
Make sure there is no debris or water inside the tank.

The water must be pumped out, not poured out, overturning the body.

With the possible appearance groundwater, the structure is attached anchor bolts, or even poured from above with ready-mixed concrete so that the top of the concrete plane is 200 mm higher than the lower stiffening rib of the equipment.
After all the manipulations are performed backfilling up to two collectors: pressure and gravity.
Then the power supply and the pipeline are brought in.

Backfilling is carried out evenly along the circumference of the pump station, sifting out stones and tamping layers of 50 cm, at a positive temperature, by pouring water. V winter time keep in mind that the soil must not freeze through.

Attach the cover, ventilation, etc. with the supplied parts.

The abbreviation KNS, which is poorly understood for most ordinary people, sounds like a sewer pumping station... Let's take a step-by-step look at what a SPS is, on what principle such stations work and how in general outline you can calculate the unit. And with homemade ones, I will show and tell you 3 options for installing the station with my own hands in the photo.

Semi-professional station KNS is perfect solution for a private house.

What are stations for?

In general terms, sewage pumping stations serve to collect and redirect wastewater to the place of their additional treatment and disposal, for example, to a septic tank of a private house or a common sewer main.

Who might be interested in the station

In fact, the range of application of automatic sewage stations is quite wide, I will only voice the most common options for a predominantly domestic direction.

If in your multi-storey building the ancient, long-obsolete sewage system, which is constantly clogged with any little things, then installing a small station in a plastic case can save the day, because it will turn all the garbage into a homogeneous mass and push it further into the system;
The story is the same if the house is in a low place, and the sewer is quite far away. Here, a similar unit is useful in that it can forcibly push the drains over a certain distance;
Arrangement of small cafes and various offices in basement floors and basements multi-storey buildings has long become the norm, but almost half of such places are below the level of the city sewage system. Accordingly, a device is needed that will raise the drains by the desired height and send it to the sewer - this is the SPS.

Remember - any SPS station is a volatile complex, since an electric pump is installed there. Many people confuse stations with septic tanks, but this is far from the same thing, although in some models of septic tanks the sewage pumping station is part of the system.

Standard operating principle

A typical project works like this:

There is some sealed container, the sizes of this container can be from several liters to several cubic meters. Wastewater flows into this closed tank by gravity;
When the drains fill the container to a certain level, the filling sensor is triggered and the fecal pump starts to work. Almost all sewage pumps for sewage pumping stations are equipped with grinders;
Then the pump pushes the crushed waste into the pipeline. But how high and far the drains can be pushed out depends on the power of the pump.

Varieties of aggregates

In the domestic sector, small stations are in the lead, which easily fit behind a toilet in a regular toilet. The body there is predominantly plastic, and a simple grinder, a filling sensor and the pump itself are installed inside. These devices can push liquid up to 5 - 7 m, which is quite enough for an apartment or office;

The household station can even fit in an apartment toilet.

In private homes, semi-professional stations are often used. There typical project is completed with at least two pumps and a mass of sensors. The price for them is several times higher than for household models, but the capacity there also corresponds to the cost, plus the volume of the receiving tank starts from a cubic meter;

A typical sewage pumping station for private houses may include a wastewater treatment function.

The so-called modular sewage pumping stations already belong to professional units, they are assembled from separate modules and can be expanded indefinitely, but they are not of interest to us, since they are not used in everyday life and even in large private houses.

The power and dimensions of modular stations do not provide for domestic use.

Modern semi-professional sewage pumping stations for private houses can not only clean and pump domestic waste, they can even handle wastewater storm sewer and drainage system.

On a semi-professional sewage pumping station in a private house, you can tie a storm drain, drainage and household drains.

Simplest station calculation

Calculation of the SPS station, especially a semi-professional one, is troublesome and here you cannot do without serious knowledge, but there is more simple instruction, it is, of course, not so accurate, but for a small private house it is quite suitable:

According to the standards, 1 person uses about two hundred liters of water per day. Count the number of people in your house and add a couple more people to the supply;
Each unit has specifications having water consumption data on hand, you can easily select the required model;
As for lifting the water to the top, 1 meter of vertical flow is equal to 2 meters of horizontal advance. In other words, if the passport says that the unit can lift liquid to a height of 8 m, then this means that horizontally it will be able to transport liquid by 16 m.

But these are all primitive calculations, suitable only for household sewage in small house, if you plan to install a sewage pumping station with the connection of a storm sewer and a drainage system, then you cannot do without the help of professionals.

It is better to pay once to a specialist than to understand after purchase and installation that you made a mistake. Moreover, now the calculation with reference to the place will cost 2 - 3 thousand rubles.

3 options for self-installation of the station

Installation of a pump station in the domestic sector is not as difficult as it might seem. Next, we will look at how to install a small plastic station indoors, as well as mount a factory and homemade station for a private house.

Option No. 1. Installation of the station indoors

Illustrations	Recommendations
	Parameters Grundfos Sololift 2 . I took the most popular mini Grundfos station Sololift 2. · The volume of the pumped-over liquid - 8.94 m³ per 1 hour; · Level of liquid expulsion vertically - 8.5 m; · Electric power of the pump 620 W; · KNS is equipped with a grinder; · Costs about 18 thousand rubles.
	. · Screwdriver; · Perforator; · Hacksaw for metal; · Roulette; · Pencil; · Level.
	... The floor under the station should be perfectly flat, and most importantly, strictly horizontal.
	. Since the device is located behind the toilet, the toilet is connected directly through a separate entrance. And to connect, for example, a sink, you need a separate pipe. And this sewer pipe is exposed with a slope of 3 cm per 1 running meter.
	External drain connection. Stage 1. Unscrew the side cap.
	... In the plug, you need to cut a hole for the drain with a knife.
	... Inside there is check valve, you need to check its serviceability with your finger.
	... Then we put a soft corrugation on the plug and fix it with a clamp. Likewise with back side the corrugation is fixed to the drain pipe.
	We put the outlet pressure pipe. Stage 1. The main rule is that the pipeline does not have sharp corners during installation.
	... The outlet for the pressure pipe in this model can be led out in 2 directions. The photo on the left shows the side outlet.
	... If desired, the outlet pipe can be connected from above.
	... You need to select some one output, and close the unnecessary one with a stub.
	... Then we cut out the inlet in the lid.
	... We close the cap and connect the soft adapter through the clamp.
	... The outlet pipe is connected through a tee and in this tee from the bottom there is an emergency drain plug, so it must be tightly closed.
	... We fasten the body of the device to the floor.
	... The toilet is connected in the same way as the side drain, that is, through the corrugation, using a clamp.
	... Now it remains to fix the toilet and connect the unit to the network. By the way, the KNS is connected via an automatic machine.

Option number 2. How to mount a factory station for a private house

The plant's sewage pumping station is a multifunctional unit, this station provides not only pumping and crushing of effluents, but also the purification of these effluents.

Illustrations	Recommendations
	. There are quite a lot of such units now, from our models the Astra pump station and the Topas station stand out. Although, in general, both domestic and imported models have similar characteristics. The cost of the station for a house of 6 residents starts at 80 thousand rubles.
	. First, the place is determined and a hole is punched in the basement or foundation under drain pipe with a diameter of 100 mm. We mount the line at an inclination of 3 cm per meter. It is better to take an orange pipe for outdoor work. It is supposed to bury below the freezing of the soil, but it is deep, so it is easier to dig in 50 cm and insulate the line separately.
	... Naturally, the pit needs to be prepared a little more than the dimensions of the unit itself, about 20 centimeters on each side. In order not to be mistaken, it is better to knock down the template in advance.
	... The walls of the pit need to be strengthened with something, in this case it is enough wooden box and a compacted sand cushion on the floor, since later the station will be insulated and filled up.
	... If the walls are plastic, which happens quite often, then the empty unit weighs up to 100 kg, respectively, 3-4 adult men will easily lower it into the pit.
	. In most stations, a specific tapping point is not indicated, there is simply an area where a drain pipe can be cut. It was not in vain that we first laid the line, and then installed the SPS, it’s easier to get to the desired area. A hole in the wall of the station is cut with an ordinary jigsaw, after which an adapter is inserted there.
	... There is nothing complicated here, just the pipe is inserted into the socket of the adapter and the joint is sealed with silicone.
	... It is better to solder the joint between the plastic housing of the KNS and the plastic adapter with polypropylene solder using construction hair dryer(500 ° C).
	... The pressure outlet is mounted in the same way, but here a pipe with a diameter of 50 mm is sufficient.
	... The station, as well as the input and output lines, are insulated with foam. For the box, 100 mm thick sheets are enough, the pipes are insulated using semicircular foam cocoons.
	. Each station model has its own connection features, but the passport must contain detailed instructions. As for laying the cable from the house to the unit, it is advisable to start it in plastic pipe or at least in a corrugation. Below in the video in this article, everything is shown clearly.

Option number 3. How to make a homemade station

Illustrations	Recommendations
	. There are several options - you can assemble the formwork and fill in a solid reinforced concrete cocoon, but this is difficult and time-consuming. You can take steel pipe large diameter, weld the bottom and waterproof the container, but this container will be heavy and not cheap.
	. It's simple: We put on the bottom of the container submersible pump with built-in grinder; We remove the pipe from the pump into the sewer line, septic tank or drain hole; · And we cut the drain from the house into the same container.
	Procedure. Stage 1. First, we dig a pit.
	... We bring the drain from the house and seal the gap.
	... The pressure pipe is cut with an adapter.
	. We hang the submersible pump with a chopper on a rope so that it can be pulled out for maintenance. To connect the pump, we cut a moisture-proof outlet into the board, and for the pump to work, we automatically install a float switch.
	... Then we act in the same way as in the case of the factory sewage pumping station, that is, we insulate with foam and fill the remaining place with sand.

Conclusion

The main unit of any sewage station is a fecal pump with a grinder.

In situations where it is impossible to provide the required slope sewer pipe, the gravity drainage scheme does not work. In these cases, a sewage pumping station is indispensable, providing an unobstructed outflow and recycling of waste.

There are two types of units: mini-stations and full-featured complexes for home maintenance. Let's figure out which option is better to give preference to, what characteristics should be considered when choosing. In addition, we describe step by step technology installation and operating rules of the sewer station.

A sewage pumping station (SPS) is an integral complex of hydraulic equipment, which is designed to pump storm water, industrial and domestic wastewater, when their gravity drainage is impossible.

Pumping stations can have an additional horizontal cavity for spreading sediment on larger area, which allows less frequent cleaning of sludge

SPS is used mainly in such cases:

The geodetic level of tanks and pipelines from which wastewater is discharged is located below the sewer or cesspool.
Lack of physical ability to organize rectilinear gravity drainage or small, threatening its regular clogging.
Far location of the cesspool or central sewer from the source Wastewater.

Equipped with pump station cottage villages, country houses, as well as industrial facilities located far outside the city and far from the centralized sewer network.

Sewer station classification

The sizes of domestic sewage pumping stations can be very different. They can fit directly behind the toilet and immediately pump drains from it in the required direction, or they can look like horizontal cisterns dug into the ground with a volume of tens of cubic meters.

But the SPS differ not only in size. Below are the classifications of pumping stations for sewage according to various parameters.

By installation type:

Vertical.
Horizontal.
With self-priming pumps.

The last type of sewage pumping station assumes forced pumping of waste water into the station building, and their removal from it after cleaning.

A sewage pumping station is used in cases where it is necessary to raise from a depth sewerage and send them down the main drain. In this situation, the task was to forcefully pump the wastewater coming from the bathhouse into the central sewerage system with the help of the sewage pumping station. Initially, the customer wanted to supply, but had to be dissuaded, since TOPAS will not work if it does not get enough food for bacteria.

Real sewage pumping stations cost from 100 thousand rubles, we offered the customer an option similar to the standard sewage pumping station and made a non-standard one. In a standard sewage pumping station, 3 or more sewage drainage pumps with cutting devices are installed. We installed one drain pump with a knife inside the tube. Collector well Alta Plast Tuba a good option for organizing a SPS with your own hands. This tube is a model Alta Plast Tuba - 2.400, 2 meters high, in fact 210 cm with a sealed bottom and a closing lid.

How to choose the right sewage pumping station

In order for the pumping station for your sewage system to be as efficient as possible, you should choose it deliberately, guided by the criteria that we will outline below.

When choosing a station for your home, remember that there is no point in buying overly powerful and, therefore, much more expensive equipment, the capabilities of which will be used by a third or even a quarter, is completely absent. The selected unit must be optimal and fully meet the needs of your home. To this end, the following parameters must be taken into account:

The distance to which the wastewater is to be pumped.
The maximum volume of waste water to be processed.
Wastewater pollution level and their structural and qualitative composition. So, in the presence of large fractions in them, it makes sense to purchase such a SPS, which includes a grinder, which practically excludes the likelihood of blockages.
The height difference between the station entrance and the place where the drains are fed.
Equipment dimensions.
The required level of wastewater treatment.

There are no universal formulas used to calculate equipment performance. For this reason, you should use the calculation algorithm, which, as a rule, is set out in the instructions attached to a particular SPS.

The calculation of the required capacity of the station is carried out in the following sequence:

the daily consumption of water in the house and the volume of generated wastewater are determined;
an approximate schedule for the flow of wastewater is built for a daily period;
the maximum and minimum values of the sewage flow are calculated;
the required capacity of the pumping station is determined, taking into account the pollution of the effluent.

Having correctly identified the parameters listed above, you can accurately select the optimal equipment that will fully satisfy the needs of your home.

We have already spoken about the size of prices for sewage pumping stations a little higher. Now we want to clarify that the price is a rather eloquent indicator:

brand popularity;
maintainability of the product;
opportunities service equipment.

You should not give preference to cheap units if their operation will be daily and if there is no additional pump equipment for evacuation and drains and there are no reserve tanks.

How to install KNS

To begin with, we deliver the materials and tools necessary for installation to the installation site. We begin to dig a foundation pit for the sewage pumping station and ...

In parallel, we install an outlet inside the tube to supply power to the fecal pump. A hole is drilled with a perk and the cable is threaded through the corrugation. The cable is mounted to the socket, and the socket is screwed onto the self-tapping screws to the walls of the tube.

The outlet pipe was already in the trench and led out into the central sewer, it remained to connect it to the station. We are digging a foundation pit for the installation of a sewage pumping sanitation.

When the foundation pit is dug to the required depth, in our case it is 225 cm, we do sand pillow and level the bottom of the pit. We lay the guides for lowering the reinforced concrete slabs.

By this time they give us a lift reinforced concrete slab, with the help of which we will anchor our ashgregat. Since the crane was physically unable to enter the courtyard, we manually transported the slab for about 30 meters.

The reinforced concrete slab is in place, you can start lowering the tube into the pit.

Another good thing about the tube is that it is light, since it consists only of plastic, we easily lowered it and put it in place. Further, with the help of a cable, the tube was securely fixed to the reinforced concrete plate. Now you can start the discharge pipe (PND 32) and start burying.

The tube is buried, of course, with sand so that the backfill is dense. Fits electrical cable in the trench.

To insert the supply sewer pipe into the station body, it was necessary to drill a hole for the jigsaw blade myself. A circle was cut and wound up with a rubber seal.

It remains only to bury ...

pumped out the incoming drains.

SPS closed with a lid.

The HDPE 32 outlet pipe in the house is led into a gray sewer pipe 50 through a transitional rubber band, which provides reliable fastening and tightness.

In general, the customer was satisfied with the work done and promised to recommend us to his friends.
